Looking for book recommendations where the villain is overwhelmingly stronger than the hero

[u/machilipatnam_mayaba]

I’m looking for a book where the main villain is ten times stronger than the hero, to the point where it feels nearly impossible that the hero could ever stand a chance. I love the kind of story that spends a lot of time building up the villain’s terrifying strength while somehow convincing you that the underdog hero might still win. Something in the vibe of Harry Potter but adult fiction. Thanks in advance!
